A'CORPORATION OF NEWV YORK.

TYPE-WRITING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 790,652, dated May 23, 1905.

Application filed July 2, 1904. Serial No. 215,052.

To all whom it 711 017 conccrn- Be it known that I, STEFANUS NIELSEN, a

' subject of the King of Sweden and Norway,

and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type- VVriting Machines, of which the following is a specification.

This invention relates to type-writing machines, and has for its main object to provide a support for the paper on which erasures may conveniently be made.

Another object is to provide a simple and efficient construction which may be readily employed in connection with the paper-guiding means of the Monarch machine. 6

Other objects will appear hereinafter.

1n the accompanying drawings, Figure 1 is a top plan view of the platen and platen-frame of a type-writing machine, showing my invention embodied therein, certain parts being omitted for the sake of clearness. Fig. 2 is a sectional side elevation taken on the line w w of Fig. 1. Fig. 8 is a fragmentary front elevation showing the erasing-shelf broken away and its relation to the platen and paper guiding and supporting means. Fig. 1 is a perspective view of one of the supporting-collars of the erasing-plate.

In the drawings, 1 is the top plate of the machine, and 2 one of the posts for the guid ing and supporting rails 3 of the platen-carriage 4. The grooved back bar 5 of the platencarriage cooperates with the rails 3 through roller-bearings, and the side bars 6 and 7 serve as bearings for the axle 8, which supports the platen 9. The paper,which is represented by the dotted line 10, is fed around the platen in a manner well understood, being sustained and guided by the paper-table 11, the feed-roll 12, and the paper-apron 12". The side bars 6 and 7 are formed with standards or lugs 13 andl i, in which are fixedly secured the ends of a removable paper-finger-supporting rod 15, which is arranged above and lengthwise of the platen. Slidably mounted upon the supporting-rod 15 are the paper-fingers 16, each comprised of a guiding part proper,

16, an offset supporting-arm 16 a neck 16, connecting the said supporting-arm with a hub portion 16, surrounding the rod 15, and, lastly, a thumb-piece 16 Each of the paperfingers is. pressed toward the platen by a spring 17,which surrounds the rod 15 and has one end terminating on the hub 16 and the other in a collar 18. The paper-fingers have a loose tongue-and-groove connection with their supporting-rod, so that they have a limited movement angularly of said rod, as well as a movement longitudinally thereof. means of the thumb-pieces 16 the paper-fingers may be slid along the rod or bar 15 to any desired position longitudinally of the platen.

- The parts hereinbefore described are substantially the same as the corresponding parts found in the Monarch type-writing machine, and it is therefore not deemed necessary to describe them with any greaterparticularity.

The erasing table or shelf 19 is composed, essentially, of a broad plate-like blade. A collar 20 is attached to the erasing-plate at each end in any suitable manner, as by soldering. The collars 20 preferably surround the rod 15 and may be held in afixed angular relation therewith in any suitable manner, as by the tongue-and-groove connection shown in the drawings, the tongue being on the rod or bar 15 and the groove in the collar. (See Fig. 4.) i

The erasing-plate may be held in a fixed relation with the rod 15, longitudinally considered, as by a small set-screw 21, which is screwed hrough one of the collar portions 20 and into contact with the supporting-rod. It will be noted that in this construction the erasing-plate is separate from and independent of the supporting-rod 15, although it is preferably supported at its ends on said rod.

As best appears in Fig. 2, the erasing-plate is supported at a comparatively short distance above the platen and slightly to the rear of its axis, the blade extending downwardly and forwardly in the general direction of the delivery ends of the paper-fingers 16, so that as the paper is delivered from the machine it passes out over the face of the erasing-table and close to the latter.

Each paper-finger 16 is formed or provided with a notch or cut-away 22 at about the junction of the supporting-arm 16 and the neck 16. This notch 22 surrounds the rear edge of the erasing-table and enables the supporting-arm of the paper-finger to be brought forward and over the table, so that the paperfingers may be freely slid along their supporting-rod without being interfered with by the erasing-table. Viewed from the position of the operator the paper-finger rod is covered by the erasing-plate, Fig. 3.

It will be noted that the invention as illustrated and described may be applied to the Monarch type Writing machine without changing any of the parts of the latter other than notching the paper-fingers. It is to be understood, however, that the invention is not limited to the particular construction aforesaid, but that it may be adapted to other forms of Writing-machines and that various changes may be effected within its scope.

What I claim as new, and desire to secure by Letters Patent, is

1. In a type-writing machine, the combination of a paper-table, a platen, a platen-frame, a rod mounted in said platen-frame, and an erasing-plate independent of said paper-table and said rod and mounted on said rod.

2. In a type-writing machine, the combination of a paper-table, a platen, a platen-frame, a rod mounted in said platen-frame, and an erasing-plate independent of said paper-table and said rod and having collar portions by which it is mounted on said rod.

3. In a type-writing machine, the combination of a paper-table, a platen, a platen-frame, a rod mounted in said platen-frame, and an erasing-plate independent of said paper-table and said rod and removably mounted on said rod Wholly forward of the latter and incliningdownwardly' 4.. In a type-writing machine, the combination of a platen, a platen-frame, a paper-finger rod mounted in said platen-frame, a paper-finger, and an independent erasing-plate mounted on said rod, said paper-finger being freely movable on said rod.

5. In a type-writing machine, the combination of a platen, a paper-finger rod mounted above said platen, and an independent erasing-plate mounted on said rod, so as to cover the rod when viewed from the operators position in front of the machine.

6. In a type-writing machine, the combination of a platen, a platen-frame, a paper-linger rod mounted in said platen-frame, a paper-finger on said rod, and an indepei'ident erasing-plate also mounted on said rod so as to cover the rod when viewed from the operators position in front of the machine, and said paper-finger passing forward over the face of said erasing-plate.

7. In a type-writing machine, the combination of a platen, a platen-frame, a paper-linger rod mounted in said platen-frame, a paper-finger, and a suitably-mounted independent erasing-plate, said paper-linger being freely movable on said rod and over said platen.

8. In a type-writing machine, the combination of a platen, a flatten-frame, a paper-finger rod mounted in said platen-frame, a paper-finger provided with a supporting-arm, and a suitably-mounted independent erasingplate, said paper-finger havinga notch orcutaway which surrounds the rear edge of said erasing-plate and enables the supporting-arm of said linger to be brought forward over said erasing-plate.

9. In a type-writing machine, the combination of a platen, a platen-frame, a paper-linger rod, a paperdinger having a hub or bearing surrounding said rod, a coiled spring also surrounding said rod, and asuitably-uiounted independent erasing-plate, said paper-linger being freely movable on said rod and over said plate.

10. In a type-writing machine, the com bination of a platen, a platen-frame, a paper-linger rod, a paper-linger having a hub or hearing surrounding said rod, and a suitablymounted independent erasing-plate, said paper-finger being freely movable on said rod and over said plate.
